Planning & Cost

EZE-Breeze Three-Season Room vs. a Full Sunroom

One extends your season by months for a modest cost. The other adds conditioned living space — and a considerably bigger job.

What EZE-Breeze actually is

EZE-Breeze panels are vinyl glazing panels that slide within a light frame and sit in the same openings as screen. Closed, they cut wind and rain and hold usable warmth on a sunny winter day; open, you're back to a screened porch. They are not insulated glass and the room is not conditioned. That's the point — the cost is a fraction of a sunroom and the porch keeps its porch character.

What a true sunroom involves

A conditioned sunroom means an insulated floor system, insulated walls and roof, thermal glass, and HVAC capacity to serve it. It typically means a permit path closer to an addition than a porch, and it changes the heated square footage of the house. It also means the space is usable in August and February, which a three-season room isn't.

  • Three-season EZE-Breeze — roughly nine to ten usable months, modest cost, keeps porch feel.
  • Full sunroom — twelve months, higher cost, adds conditioned area, more permitting.
  • Convertible approach — build the shell to sunroom standards now, glaze it later.

Converting an existing porch

Most of our conversions start with an existing screened porch. EZE-Breeze usually drops into that structure with minimal changes. Converting the same porch to a conditioned sunroom is a different scope: the floor, the roof insulation and often the foundation all need to be addressed. We assess which path your existing structure supports before anyone falls in love with a plan.

Which one we recommend, and when

If the goal is more evenings on the lake in March and November, EZE-Breeze is almost always the better value. If the goal is a room your family lives in year-round with the rest of the house, build the sunroom properly rather than trying to heat a porch.
